The reliability and small size of solid state scanners makes them ideal for LIDAR. We fabricated and demonstrated the successful operation of an optical scanner using silicon photonics integrated circuit technology. The scanner comprises a ring resonator multiplexer and a number of grating arrays, and employs a beam switching method, which means that the scanner is movement-free. The multiplexer determines the optical path and light is emitted from the selected grating. The scanning angle obtained was 6 degrees. LIDAR sensors can be used in automotive applications for automated cruising.
固态扫描仪的可靠性和小尺寸使其成为激光雷达的理想选择。我们利用硅光子集成电路技术制造并演示了一种光学扫描仪的成功运行。该扫描仪包括一个环形谐振器复用器和多个光栅阵列，并采用光束切换方法，这意味着该扫描仪无需移动。复用器确定光路，光从选定的光栅发射。获得的扫描角度为6度。激光雷达传感器可用于汽车应用中的自动巡航。
